I think Boris's point is that the definition has to be written such
that the value of CSS properties has no influence on whether
selectors match.  At least I hope that was his point.

(The definition of which elements should match :disabled could
perhaps be left to the underlying markup language.  However,
Lachlan's definition clearly allows too many factors to influence
that matching.)

Whether an element is display:none absolutely cannot change whether
it matches disabled; otherwise we'd have big problems with
  :disabled { display: inline ! important; }
